Someone do a micro LPF
Coming from the mini multirotor area, we seem to be proficient at occasionally casting these little quads into the wind and that's the end of that.
The commercial lost plane finders I've found aren't suitable for these little guys. Weigh too much and generally plug into balance connectors. Our little guys mostly fly on 1S, so no such connector.
I'm no EE but knew several before I retired and I would think this would have been child's play for them. Take a pulsing piezo buzzer and throw together a little circuit to start when powered up, time for maybe 10 minutes, then turn on the buzzer. No matter if it eventually runs down the battery because if I haven't found it by then, a sick battery is the least of my problems. Reset the timer every time you do a power interrupt.
Could splice it into the FC power pigtail, or install via sandwich connector between FC and battery. No reason it wouldn't work on micro fixed wing too. If someone could put these out for not too much $$, I'd bet there's a local market for them.

As this is the DIY forum see this;
Problem with real small beepers, running off low voltage, is making them loud enough, not so easy.
